Phone dialing numbers by itself

I have Polycom phones that are self-dialing clients and intercoms.

This is very aggravating as this process never stops. Client and customers are getting non-stop calls from our phones and there is nothing we can do to stop the calls. It is as if the phones have been hacked or Casper the ghost is in our office.

Technical Support is not helpful at all, as I keep getting the same girl who is reading answers from a manual...

Is anyone else having this issue?

I have heard of this a few times, but the only way I can imagine it happening is if your network is not configured correctly/securely.  Do you work on the network and know how your firewall is configured?  You should have *no* inbound port forwarding to phones.  If your phones are visible via the public internet they will be hacked.  I would start by reviewing your firewall settings or asking your network person to.

Our network is protected by Fortinet Firewall. No inbound ports have been forwarded to the phones.

Are these phones purchased from RC or you provided them?

I would review this or share with your Fortinet vendor: https://success.ringcentral.com/articles/RC_Knowledge_Article/9233
Notably:
In a stateful firewall, no inbound ports need to be opened because they are automatically opened upon a reply to outbound traffic initiated by the RingCentral endpoint in the local network.

The phone were rented from RC.

As stated, there are no ports opened to the phones. We have one phone that was re-provisioned as it was self dialing. It is doing it again... this time we took videos of the issue. RC has sent out a replacement phone....

This is strange indeed.  If you haven't opened a support case yet, can you please do so?  Please include the most recent samples (dates, times, #s etc) in the case notes.

I have this issue with a VVX-500 purchased from Ring Central. It does it every day and dials my other phone and records whatever is going on in the room with the other phone until the recorder for a voicemail stops. Then you can go back and listen to what was recorded. Strange! Today, 12/29/17, it has done it 5 times.

We had this problem with VVX-500's as well. The fix was to remove the extensions from the HUD. According to support, there is a bug in the 500's soft-keys that causes this anomoly.
